Bill Cosby by far is the greatest of those mentioned and I would say the ONLY sane one of the entire group. Robin Williams has to OVER-act to be funny; Ricky really isn't funny in my opinion, Ellen used to be funny until she admitted just how "funny" she really is; Jerry Seinfeld has to feed an ego problem and is too damn cocky; And then there was this black lady that decided that Ellen's way of being "funny" was also good for her; and well Billy Crystal, how could you laugh at such a painful disguise of a so-called male comedian? Bill Cosby is the ONLY REAL human comedian and the others shouldn't even be listed. They fit more in the animal category.

It says a lot when you have an entertainer who can have everyone laughing without having every other word an "f-bomb", no blasphemy or crude sexual jokes. It is a rare talent and speak volumes about Bill Cosby's character.

I really wish there had been All of the Above. I remember Bill Cosby as Himself, and seriously nearly ruptured my spleen laughing when I saw that. But Robin Williams kills me, too. I have never heard of Ricky Gervais or Wanda Sykes, but Billy Crystal and Jerry Seinfeld are great, also. If you have never seen Bill Cosby as Himself, it is a DVD, and you should rent, buy or see it.

Of course, you should have added Peter Sellers, inarguably the funniest man to EVER live.
